分岐型サプライチャンバー１は、本体１０と角筒型接続部２０とを備えてなる。
本体１０は、筒壁部の径方向の一方の側に設けた開口部１１を入口とし、軸方向の各端部を分岐出口１３とし、軸方向が径方向よりも長く形成された円筒状をなしている。
角筒型接続部２０は、円筒状の本体１０の開口部１１に、筒壁部から突出するように設けられている。筒壁部からの突出程度（長さ）は適宜設定することができる。
円筒状の本体１０及び角筒型接続部２０は、それぞれ骨格をなす内面材として亜鉛鋼鈑等の金属板材１０ａ，２０ａにより構成され、かつ好ましくは、保温材による被覆層１０ｂ，２０ｂを有する。保温材としては、例えば、グラスウール、ロックウール、セラミックウール等の不燃性材料が用いられる。また、最外層には、通常、保護層１０ｃ，２０ｃ、例えば、アルミ箔又はガラスクロス単体あるいは前記アルミ箔とガラスクロスや、アルミ箔とクラフト紙等の複合体のような表面強度を向上するための保護層、あるいはコートによる表面強度を向上するための塗膜による保護層が形成される。
この保護層は、保温材に直に密着された態様で形成する（例えば、グラスウールフェルトその他の保温材の外層に貼着する、又は保護層が既に外面に貼着された保温材を金属管に巻き付ける）他、保温材の外側に保護層として被せて覆うことより形成してもよい。 The branch type supply chamber 1 includes a main body 10 and a rectangular tube type connecting portion 20.
The main body 10 has a cylindrical shape in which the opening 11 provided on one side of the cylindrical wall portion in the radial direction is an inlet, each end in the axial direction is a branch outlet 13, and the axial direction is longer than the radial direction. There is no.

As the heat insulating material, for example, nonflammable materials such as glass wool, rock wool, and ceramic wool are used. Further, the outermost layer usually has a protective layer 10c, 20c, for example, aluminum foil or glass cloth alone or to improve the surface strength such as a composite of aluminum foil and glass cloth or aluminum foil and kraft paper. A protective layer of a protective film or a coating layer for improving the surface strength by coating is formed.
This protective layer is formed in a form that is in direct contact with the heat insulating material (for example, a heat insulating material that is adhered to the outer layer of glass wool felt or other heat insulating material, or the protective layer is already adhered to the outer surface is attached to the metal tube. In addition, it may be formed by covering and covering the outside of the heat insulating material as a protective layer.

円筒状の本体１０の骨格をなす金属板材１０ａとして、螺旋状に連続製筒された空調用ダクトを利用して構成したものが好ましい。既存の空調用ダクト（材料としての）を利用することができる利点がある。特に、既存の空調用ダクトとしては、螺旋状に連続製筒されたダクトに前記した保温材による被覆層１０ｂ及び保護層１０ｃが形成された種々のサイズのものが広く製造されているので、これをそのまま本体１０として利用するのがより好ましい。これにより大幅なコスト削減が可能である。
また、円筒状の本体１０の金属板材１０ａとして、パンチングメタルのような多孔状をなすものを使用することにより、消音効果を発揮させることができる。 As the metal plate member 10a forming the skeleton of the cylindrical main body 10, a metal plate member 10a configured using an air-conditioning duct continuously formed in a spiral shape is preferable. There is an advantage that an existing air conditioning duct (as a material) can be used. In particular, as existing air-conditioning ducts, various sizes having a coating layer 10b and a protective layer 10c of the above-described heat insulating material formed on a duct continuously formed in a spiral shape are widely manufactured. Is more preferably used as the main body 10 as it is. As a result, significant cost reduction is possible.

角筒型接続部２０は、円筒状の本体１０の軸方向を長辺とする横長の矩形状に形成されており、かつこの矩形状に形成された開口部が、接続対象となる個別空調機の出口部に適合する大きさに形成されている。このため、角筒型接続部２０をジョイント部として個別空調機へ直接接続することができるので、施工の際の作業をきわめて簡単に行うことができる。
角筒型接続部２０は、円筒状の本体１の筒壁部に穿設した開口部１１に適合する大きさに形成され、例えば、図３（ａ）に示すように、角筒型接続部２０の基端部に屈曲形成した外フランジ部２１にて鋲やネジ等によって取り付けるか、あるいは図３（ｂ）に示すように、角筒型接続部２０の金属板材２０ａをく字状取付片２５を用いて鋲やネジ等によって取り付けるようにすればよい。
角筒型接続部２０が設けられる円筒状の本体１０の開口部１１は、図２（ｂ）に示すように、軸方向の各端部から所要の長さＴを置いて形成するのが好ましい。これにより、本体１０の剛性を確保することができる。 The rectangular tube-shaped connecting portion 20 is formed in a horizontally long rectangular shape having the long side in the axial direction of the cylindrical main body 10, and the opening formed in the rectangular shape is an individual air conditioner to be connected. It is formed in a size that fits the outlet portion of the. For this reason, since the square tube type connection part 20 can be directly connected to the individual air conditioner as a joint part, the work at the time of construction can be performed very easily.

The outer flange portion 21 is bent at the base end portion of the base plate 20 with a flange or a screw, or as shown in FIG. 3B, the metal plate member 20a of the rectangular tube type connecting portion 20 is attached in a square shape. 25 may be attached by using a hook or a screw.
As shown in FIG. 2B, the opening 11 of the cylindrical main body 10 provided with the rectangular tube connecting portion 20 is preferably formed with a required length T from each end in the axial direction. . Thereby, the rigidity of the main body 10 can be ensured.

図４に、前記したような分岐型サプライチャンバー１を用いた空調系統の接続例（接続配管システム）を示す。
分岐型サプライチャンバー１はその角筒型接続部２０にて個別空調機５に接続されている。分岐型サプライチャンバー１の軸方向の各端部の分岐出口１３，１３には１次ダクト４０，４０が直接に接続されている。分岐型サプライチャンバー１の円筒状の本体１０の径（内径）は、この１次ダクト４０の内径と同等に形成されており、図２（ｂ）に示すようにニップル（管継手）３０を両ダクトに差し込むだけで互いに連結することができるようになっている。
１次ダクト４０，４０は、比較的長さの短い円筒状に形成されており、１次ダクト４０，４０にはそれから分岐する２次ダクト５０，５０が接続されている。１次ダクト４０と２次ダクト５０はほぼ同径に形成されている。２次ダクト５０の筒壁面に、１次ダクト４０の軸方向下流端部がＴ字状をなすように接続され、１次ダクト４０から流入するエアは２次ダクト５０において直交する二方向に分流する。そして、２次ダクト５０，５０には、吹出口７０へ接続される適宜複数の３次ダクト６０，６０が接続されている。３次ダクト６０は、２次ダクト５０よりもやや小径に形成されており、またフレキシブルダクトを用いており、末端部の三次ダクト６０はその屈曲性を利用してエルボ仕様となっている。
しかして、個別空調機５から角筒型接続部２０を介して円筒状の本体１０に導入されたエアは、円筒状本体１０内において、直交する二方向に分岐して１次ダクト４０，４０へ流れ、さらに１次ダクト４０から直交する２次ダクト５０で二方向に分岐した後、２次ダクト５０からこれに接続された３次ダクト６０を介して各吹出口７０へと供給される。
ここで、１次ダクト以下の下流ダクトについては、例えば、１次ダクト・２次ダクトあるいは２次ダクト・３次ダクトといった組合せの範囲内で適宜、工場でユニット化し、施工現場へ搬入するように構成することができるため、そうすることにより、施工の際、接続箇所が減り、作業工数が削減され、工期の短縮を図ることができ、全体的なコストパフォーマンスの向上を図ることができる。 FIG. 4 shows a connection example (connection piping system) of an air conditioning system using the branched supply chamber 1 as described above.
The branch type supply chamber 1 is connected to the individual air conditioner 5 at the rectangular tube type connecting portion 20. Primary ducts 40 and 40 are directly connected to the branch outlets 13 and 13 at the respective axial ends of the branch type supply chamber 1. The diameter (inner diameter) of the cylindrical main body 10 of the branched supply chamber 1 is formed to be equal to the inner diameter of the primary duct 40, and as shown in FIG. They can be connected to each other simply by inserting them into the duct.
The primary ducts 40 and 40 are formed in a relatively short cylindrical shape, and secondary ducts 50 and 50 branched from the primary ducts 40 and 40 are connected to the primary ducts 40 and 40. The primary duct 40 and the secondary duct 50 are formed with substantially the same diameter. The axial downstream end of the primary duct 40 is connected to the cylindrical wall surface of the secondary duct 50 so as to form a T-shape, and the air flowing from the primary duct 40 is divided into two directions orthogonal to each other in the secondary duct 50. To do. The secondary ducts 50 and 50 are connected to a plurality of appropriate tertiary ducts 60 and 60 connected to the air outlet 70. The tertiary duct 60 is formed to have a slightly smaller diameter than the secondary duct 50, and a flexible duct is used. The tertiary duct 60 at the end has an elbow specification utilizing its flexibility.
Thus, the air introduced into the cylindrical main body 10 from the individual air conditioner 5 via the rectangular tube-shaped connecting portion 20 branches into two orthogonal directions in the cylindrical main body 10 and primary ducts 40, 40. Then, the air is further branched from the primary duct 40 by a secondary duct 50 orthogonal thereto, and then supplied from the secondary duct 50 to each outlet 70 through a tertiary duct 60 connected thereto.
Here, for the downstream ducts below the primary duct, for example, in the range of the combination of primary ducts, secondary ducts, secondary ducts, tertiary ducts, as appropriate, unitize them at the factory and carry them to the construction site. Since it can be configured, by doing so, the number of connection points is reduced during construction, the number of work steps can be reduced, the work period can be shortened, and the overall cost performance can be improved.
